carbon oils or residues and at the same time mixing the gas produced with air.

My device is especially ada ted for use in connection with gas-enrines, ieating, lighting, or other uses for wiliioh gas may be applied. ll/"hen used to produce gas for use in gas-engines, the heat in the waste gases drawn oil' through the elhaust-pipe maybe used to convert the gasolene, distillate, crude or other hydrocarbon oils into gas for such use and for any other purpose for `which gas is desired.

My improved retort is designed to produce the maximum evaporationof the hydrocarbon oil from a minimum of heat, such heat being the waste heat from the gas-engine, a stove, or other suitable source provided for the purpose. i

Reference is to be had to the accompanying drawings, forming a part of this specification, in wlnch similar characters of reference' indicate corresponding parte in all the tigures, in which* y Figure 1 is a vertical section'through the retort. Fig. 2 is a cross-sectiony on the line 2 2 of Fig. 1. Fig.` 3 is a vertical section on the line 3 3 of Fig. f2. Fig. l is a horizontal section on the line 4 4 of Fig. 1and Fig. 5 is a diagrammatic view of a modified forni of the ap aratus.

ily improved retort comprises a main casof an inner wall 6, an outer wall 7, and a ling of insulating material 8, preferably asbestos, between the inner ,and outer walls. closed by a suitable bottom 9.and top 10, which are held together and to the casinglby long bolts 11, extending the ntire lengt of the casing between the inner and outer walls thereof. The top 1U is provided with a The ends of the casing are small pipe 12 for the admission of the gasolene, oil, or other material from which it is designed to produce the gas, a larger gas-,outs

let pipe 13, through which the gas is drawn oli to the storage-reservoir or point at which it is desired to use the same, and with a large outlet-pipe 14 for the exhaustgases which have been used. to heat the retort. The bottom 9 is provided with a large'inlebpipe 15,

through which the hot gases are admitted t0 the retort, and with a draw-cti pipe 16 iorthe heavier portions of the oil or residue which have not been evaporated and toward which the upper surface of the bottom 9 elan-ts to facilitate the drainage.

lithin the casing and 4resting upon the bottom is a column or series of pans over which the oil flows and within which the hot n gases circulate to volatilize the oil. AAll of these pans are substantially alike, and each rests upon and is carried by the 'pa1 1bel 0w,l

While the bottom one rests upon 'a Abrass plate 17 lat the bottom of an annular groove or recess 18 and the upper surface of the v Above the partition 20 and 22 of the pan, which is carried by the side l walls 21 and extends inwardly .therefrom-to the cylindrical collar 28, extendingpwardly from the bottom 22 `and substantially'in alinement withthe annular -collar 19. The collar 23 is provided with'a shoulder 24,

adapted to support the collar'lQ? of thepan i aboveand ma. T, if desired`,`"be

a screviethrea ed portion 25, l

ans may be secured together.; `The wall or bottom 22 is designed to befsupported in subrovided with 'A y.whichth'e stantially a horizontal plane, and the matei. rial to be volatilized rests on thls bottom be.

tween the outer vertical Yside wall 2.1 and the inner annular collar 23; but to permlt of the passage of this material from `onejpan .to the next Aan opening is provided thi'igh the botf tom 22 and wall 20, as shown in Figs. 2 and 3. The bottom 22 ofthe pan isvinclined upward toward the opening, so thatasmall amount of material will normally remain on the bottom of the pan Without falling through the opening, and to prevent communication between the central s ace Within. the pan and the upper surface thereof provide partitions 26, oonnecting the bottom 22 and the wall '2,0 and surrounding the disohargeopening. Surrounding the opening on the lower side is a downwardly-extending lip or iiange 27, 'which serves to prevent the material which hows through the opening from adhering to the bottom of the pan and causes it to drop directly into the pan below. Within the inner space of each pan is a horizontal partition 2S, suitably supported and extending entirely across the main axial passage of the pan and out into the space between the Wall and the bottom 22.

As the hot rise through the pipe'l the come in Contact with the partition. 28 areoaused to iiow radially toward the outer circumference oi the pan until they get beyond the edges of the partition 28 Where-- upon they How back toward. the central portion of the pan and directly in. Contact With the bottom 22 until lthey reach the central portion again, Where they may rise through the passage within the collar 23 and upward unt-i they come in Contact with the partition 28 ofthe pan directly above.

In order that the material to be volatilized may be prevented. from collecting in large uantities on the ansy should it become too t ick to iiow readi y, i provide a plurality of brushes 29, supported upon the side wall olA the easing and extending inwardly and in engagement with the bottoni 22 of each pan'. These brushes may be of any suitable design, but preferably comprise a back member 30, extending through the Wall of the easing and provided with a nut upon the outside and aving a plurality of bunches of 'wires extending dovrnvfardly and adapted to brush the entire bottom 22 of the pan as the latter rotates. As shown in the drawings, all of these brushes are in the same vertical line and all of the saine specific character', but it is evident that they may be located upon any side of the casingr desired and besupported in any suitable manner. `The openings for the passage ol the material from one pan to the next are preferably not nrrangeil in alinernent; but the opening of each pan is slight-ly behind that of the pan direrlly he low, so that the material passing through any opening strikes the next 'pan just bark of this opening, and thus has to travel nearly the entire circumference of the pan before il can pass to thel pan beyond.

For rotating the aus any suitable device may be employed; iiutprel'erably I provide a gear-wheei 31, having a dov nWardly-extending collar 19,'si1nilar to the downwardly- @einen extending collars of the ans below, and hay" 155 ing an. upwardl nenten ing collar 32 fitting Within the recess Within the top 1() of the retort and adapted to act as a journal as the. pans rotate. Supported Within the top 10 of the retort and extending through the wall 7c thereof is a shaft 33, having a worm-wheel 34, on its inner endI adapted to engage with the gear-Wheel 31, While the outer end of the shaft 33 is rovided with a pulley 35 or any other suita le means whereby it may be ro-. tated,

The side of the easing is provided with a door 36 of any suitable character and adapted to be closed gas-tight to prevent the escape of gas from the retort. rif'his door is 8o preferably made up of inner and outer Walls and intermediate insulating material similar to the easing of the retort, and as the door is normally closed it 'may be bolted in position in any suitable in anner. At the lower endl of the easing is an air-inlet pipe 37, which may be either in the wall of the casing' or in the door, as may be desired.

in the operation oi' my improved. gas-generating retort the material to be volatihzed. 9o is admitted through the pipe i2 on the upper nan, and the entire series of pans are rotated y .means oi the shaft 3.3 and worm-Wheel 34.

The pipe 1.5 is connected to any suitable source ol heating medium, preferably to the exhaust of a gas-engine, il: the gas produtedI is to be used in such engine, and air is admittedthrough the pipe 37. The nir rising around the pans niingles 'with the gas produoekl by the vaporizai n of `the material mo upon the pans, and the mixed air and gas escape through 'the pipe i3, while the exhaust heating mediui'n escapes through the pipe i4. As the pans rotate t 1e material from one pan to the next through the dischargem5 openings and iscaused to ilou' almost entirely around each pan before passing to the nent one. T he brushes facilitate the eireu lation oi the oil, and particularly in case the oil is lhirl and heavy'or the retort is (fold 11o and it first starled in operation.

it is evident that any number of pens may be employed, and in use l prefer to use a inueh larger nunillr-r than that employed in the device illuslrfiledin lhe drawings. ll" desired, no nir need be admitted through the pipe 2T, and the gas prodinfed may then be mnployefl for lighling or heal ing, jfor when air is admitted through the pipo 3T the resultant gas is an explosive mix- '12o lure adapted 'Vor use in gas-enghws, in uhh-h ease l heat the rfi-lorr l'ron'l the |Xluu1s1-gns s from the engine und., in l'aet,01rxploy it a muffler, 'ilE desired, the nir ma;l be admitted through the pipe .l and the gas produced he x25 drawn oil through the pipe 3T, and it is evident that other changes 1n the operation, as n ell as in the .epeoiio struc-ture, maybe made .vithout Vention.
